Hi setorc2, sorry to hear of your misdelete problem, but as akazrdude says all is not lost, you can still recover.
When you delete files from your hard drive, even if you empty your recyele bin, the files are still on your drive, but only hidden from us mere mortals, they are stored in sectors which are made available to be written over again, so as akazrdude says again, try not save anything to your hard disk till you run a file recovery program. I use File Recover, and it has always saved my bacon (so far).
So good luck, and I hope you manage to recover your folder.
